The Freescale hypervisor management driver provides several services to drivers and applications related to the Freescale hypervisor: 1. An ioctl interface for querying and managing partitions 2. A file interface to reading incoming doorbells 3. An interrupt handler for shutting down the partition upon receiving the shutdown doorbell from a manager partition 4. A kernel interface for receiving callbacks when a managed partition shuts down.
